[Why am I posting a weather report article here today? Because it makes
a point the climate change apologists refuse to understand. Climate
change does not lead to longer growing seasons. Due to the increased
volatility of weather, including temperatures, climate change leads to
SHORTER growing seasons. It's counter-intuitive, I know. But this is
the reality of growing seasons for most crops - it runs from the last
frost in spring to the first frost in autumn. Because of temperature
volatility brought on by climate change impacting the path of the
jetstream - especially in spring and autumn now - we get sub-zero nights
later in the spring and earlier in the autumn than was the case when
weather patterns were more stable.
This detrimental impact on growing seasons comes on top of more
droughts, more floods, more crop-damaging hail and wind storms, and
changes in when precipitation appears over the course of the growing season.
The key take-away here is that we have developed agriculture based on
12,000 years of relatively stable climate. Pretty much any change in
climate and weather patterns is going to have negative effects on the
crops we are accustomed to growing.
This specific story is about hard frosts in important crop growing areas
roughly 2-4 weeks earlier than is typical for these areas. Mitigation
is going to require shifting to crops which mature faster or more
protected growing techniques, like enclosed vertical urban crops. That
is likely one of the costs of increasing food security in the next few
years.

Ontario: Chilly start to weekend before warmth, rain return
In case the chill in the air didn't convince you, the frost advisories
in place for a good portion of southern Ontario might. *The growing
season is set to come to an abrupt end across much of the region
Saturday morning as temperatures dip under clear skies.* While the warm
air does rebound by the second half of the weekend, clouds and showers
come along with it. We take a look at how chilly it gets and take a peek
ahead to Thanksgiving weekend, below.
WEATHER HIGHLIGHTS:
Widespread frost threat early Saturday outside of urban/suburban
areas, advisories in effect
Mainly sunny skies through Saturday afternoon
Showers, milder temperatures return for end of weekend into next week
Watching for cold front, chilly showers into Thanksgiving weekend
Stay aware of ALERTS in your area
WIDESPREAD FROST AS TEMPERATURES TUMBLE
While high pressure will clear out the clouds through the start of the
weekend, sunshine won't do much to help high temperatures with many
places barely hitting the lower teens through Saturday.
"Widespread frost is likely early Saturday outside of urban/suburban
areas," says Weather Network meteorologist Dr. Doug Gillham.
"Temperatures will dip well below freezing across parts of cottage
country." Early risers will find temperatures on the chilly side, even
after sunrise.
The rain showers return by early Sunday morning ahead of a brief boost
in daytime highs. Some spots will return to the 20-degree mark for
Sunday afternoon, though spotty showers won't make this a great outdoor day.
